An unexpected error occurred: "EPERM: operation not permitted"

Question

I have installed ReactJS to work on some project but this mistakes are making me sick. First error appear when I tried to add package for my project. So , I used :

yarn add @material-ui/icons  

and after that It was fetching. And I got this error message on the terminal line :

error An unexpected error occurred: "EPERM: operation not permitted, unlink 'C:\\React\\MyProject\\node_modules\\node-sass\\vendor\\win32-x64-93\\bindiinfo Visit https://yarnpkg.com/en/docs/cli/add for documentation about this command.

I found some solutions and wanted to try. Whenever I try to use install command, it does not let me. It gives this error

npm ERR! cb.apply is not a function

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\XXXXXX\AppData\Roaming\npm-cache\_logs\2021-11-14T00_08_12_781Z-debug.log

and whenever I click this error log, here is what I see.

Answer 1

Avast Antivirus was the culprit for me. Disable it.

Answer 2

I faced same issue when I tried to install the blueprint package using yarn, I solved it by using npm package manager (npm install)

Answer 3

Please stop the development server and install or add the packages.
